Just two of these in existence, both are on outpost.

This is a counter suggestion to (3.6 - 4 buds)

Sold for Ghosts Geisha(~1.3) + Smoking Western(~19 keys) = ~2.2 buds

http://www.tf2outpost.com/trade/13676631 Buyout of 2.5 buds

Looks to have sold for Planets Swagman(~20 keys) + O. Fire Glengarry(~1 bud) = ~1.9 buds

BP History didn't leave enough data so this is purely by checking histories on outpost. Everything matches up though.
